Daniel® Orifice Fittings
Orifice Fittings operate by means of differential pressure technology. They contain
an orifice plate that restricts the flow of product through the pipeline. As fluid
approaches the orifice plate pressure increases slightly and drops suddenly as the
orifice is passed. Established procedures and calculations allow the flow rate to be
inferred from the differential in pressure.
Daniel® Senior® Orifice Fitting
The Daniel Senior Orifice Fitting is a dual-chamber device that
reigns as the most widely used means of measurement for natural
gas. Designed to allow operation by one person, this differential
technology meter saves time and money in many ways. The Senior
Orifice Fitting permits plate-changing under flowing conditions,
which translates into no operation shutdown. By maintaining flow
during plate changes, the fitting also avoids the burden of bypass
piping. In addition, the Senior Orifice Fitting is field-repairable.
That means no downtime and other costs associated with shipping
to a repair site. This fitting also offers special trims and an optional
soft seat.
Since its original development, the Senior Orifice Fitting product line
has grown enormously to serve customers with applications for
pipeline sizes from 2 inches to 48 inches, and pressure ratings up
to 10,000 pounds per square inch. In addition, the use of corrosion
resistant and other special materials makes this product suitable for
sour gas service and other special applications. Daniel's most
popular Senior Orifice Fitting, the "Flangnek®," has a weldneck inlet
and a flanged outlet. Daniel fittings meet or exceed API Chapter
14, Section 3, Part 2 (14.3/AGA 3) requirements.
Features and benefits:
High reliable, time proven technology
Fast and simple method of changing orifice plates
under pressure without interrupting the flow
Multiple sizes and pressure ratings
Special trims
Field-repairable
Optional soft seat

Daniel® Simplex® Orifice Plate Holders
Daniel® Simplex® Orifice Plate Holders
Daniel Simplex Orifice Plate Holders are single-chamber fittings that
house and accurately position an orifice plate for differential pressure
measurement.
These fittings allow the removal or insertion of the orifice plate quickly
and economically. The single chamber design allows for inspection and
replacement of orifice plates without removing the Simplex meter from
the flow line. Since Simplex fittings use one piece bodies, there is no
spillage in liquid service, no rusted stud bolts, no nuts to remove, no
flanges to spread apart and no line strain. The Simplex is designed and
manufactured in strict accordance with all applicable ANSI, ASTM, API
14.3 and ISO 5167 specifications.
Features and benefits:
Operation of the Simplex Orifice Plate Holder is simple
because of its few parts The plate carrier ring is permanently
attached to the sealing bar so that the bar, ring, plate and seal
unit can all be removed at the same time. The only other parts
are the gasket clamping bar and pipe plugs for taps and drain
Under normal conditions Daniel Simplex Orifice Plate Holders
require minimal or no maintenance at all
This Simplex Orifice Plate Holder is designed in 3 - 4 inch line
sizes for high pressure measurement in applications such as
production wells, injection systems and recycling operations.
Heavy-duty construction throughout enables the fitting to
handle pressures up to 10,000 P.S.I.
The Daniel Simplex Orifice Plate Holder uses universal size
orifice plates and removable sealing units
Standard sealing unit for the Simplex Orifice Plate Holder is
the "DSC" Nitrile Dual Seal. Additional seal material
available upon request. The type of sealing unit used will
depend on the application for which they are being used
Body styles include flangnek, welding neck, socket welding
and threaded
Simplex Orifice Plate Holders are made of cast carbon or
alloy steels, and types 304 and 316 stainless steel. Internal
parts are trimmed in a variety of metals to suit most
operating conditions
A specially designed top closure seals off the fitting

Daniel® Junior Orifice Fitting
Safety, simplicity and ease of operation make Daniel Junior Orifice Fitting
a popular choice for reliable measurement at large volume meter stations.
The Junior Orifice Fitting is a single-chamber fitting, engineered and
manufactured to make orifice plate changing quick and easy at
installations where line movement from flange spreading is undesirable.
Features and benefits
Rack-and-pinion configuration ensures fast plate changing
Saves time by avoiding flange spreading
Junior Orifice Fittings installed on liquid lines prevent product
spillage during plate changing
All parts can be replaced on location without removing the fitting
from the line
Special positioning of set screws impinges on the plate carrier on
all four edges, fixing and centering its position
The top set screw is in the sealing bar so that the fitting cannot
be sealed off unless the carrier is fully seated and centered
Versatility of line sizes from 10 to 42 inches
All fittings meet or exceed the recommendations of ANSI/API 14.3, A.G.A.
#3, A.S.M.E, and numerous other professional organizations.

Daniel® Orifice Flange Union
Daniel® Orifice Flange Union
Daniel offers a comprehensive line of Orifice Flange Unions
manufactured to ensure the highest possible accuracy in measurement,
backed by the reliability and experience only Daniel can provide. Daniel
Orifice Flange Unions provide economic differential measurement with little
or no maintenance. The Orifice Flange Union serves as an economical,
simple device for securely holding an orifice plate in a line.
Features and benefits:
Advanced machining equipment enables Daniel to meet the mos
stringent tolerances and recommendations for flanges as specified
in ANSI B16.36: Steel Orifice Flanges, and ANSI/API 2530 (AGA #3):
Orifice Metering Of Natural Gas
Careful attention is paid to the tap location, bolt and flange facings
and bore smoothness
Daniel Orifice Flanges are made of forged steel in accordance with
ASTM A-105. Other materials are available by request
Orifice Plates are centered within stringent tolerances becoming
the first plates that met the latest AGA standards
Bore tolerances meet or exceed the latest recommendations of the
American Gas Association
Pressure tap hole location is closely controlled. Tap hole centers
are 15/16 inch from bearing faces of flanges. This places the
centerline one inch from the face of the orifice plate when 1/16 inch
gasket thickness is included. For three inch and smaller flanges,
the tap hole location tolerance is ± 1/64 inch. For four inch and
larger flanges, the location tolerance is ± 1/32 inch
Pressure tap holes edge on the flange bore surface are carefully
inspected to be free from burrs. All roughness is eliminated
Standard flange tap connections are 1/2 inch N.P.T. Other sizes and
styles are available upon request
Daniel Raised Face Orifice Flanges are made to conform to the
standard raised face dimensions in accordance with the ANSI B16.5
Flange Piping Code for all pressure ranges
Two 1/16 inch thick precision die-cut gaskets are furnished with all
Raised Face Orifice Flanges. Ring type joint facing available upon
request. It is important to note that when the specified gasket
thickness is other than 1/16 inch, flange pressure tap location will
change.

Daniel® Meter Tubes
Daniel Meter Tubes are accurate and dependable instruments that
adhere to the highest quality standards. They are an integral piece
of a Daniel Orifice Meter.
Quality Fabrication
Close quality control guarantees highly accurate fabrication of Meter
Tubes for Orifice Meters. Special jigs and fixtures are used to assure
precise alignment of tube and fitting so there are no steps or offsets. All
welds are ground and micrometer readings are made.
Testing
Radiography and hydrostatic testing is available for Daniel Orifice Meters
to ensure measurement accuracy. Micrometer and internal surface
roughness readings are recorded and supplied with each meter tube.
Paint and Coating
A special quick-drying paint is applied as standard on Meter Tubes.
Sand-blasting and corrosion-resistant coatings are also available.
